splash-screen

I'm doing performance testing on my iphone app and I'm noticing that sometimes a good 3-4 secs elapse at startup before I start seeing my NSLogs from applicationDidFinishLaunching. I've optimized what happens once the code enters applicationDidFinishLaunching but I'm not sure how to optimize what goes on before that. I'm using a Default.png splash screen so it basically just stalls on that screen before it enters applicationDidFinishLaunching and starts doing something.

Just to give you guys some context, I have no nib files and I'm using core animation, if that makes any difference. I have about 10 different controllers and my total bundle size is just under 2MBs.
